By 1918, demand for plumbing extended beyond the reach of urban water and sewerage systems. Mail order enterprises, like Montgomery Ward & Company, offered consumers self-contained systems which could bring the urban amenity of indoor plumbing to country houses as well. Slowly, indoor plumbing became a part of houses in any location, not just in those located within urban, or suburban, water districts. This catalogue was designed to sell indoor plumbing beyond the bounds of urban systems.
